Monitor stuck in power saving when I boot my PC.
Short story:
Had an Rx570 GPU, it started artifacting so a friend lent me their old Gigabyte GPU. Worked for about a month, and then when I tried to turn on my PC it just stayed in power saving mode. I switched back to the Rx570 and just powered through the artifacting, and then just yesterday it fully broke. I then AGAIN switched back to the Gigabyte GPU from my friend, and behold, it worked, no power saving. That was earlier today. I turned my PC off and went about my day, came home, launched it, and I have the power saving issue again.
The fact that this issue wasn't present when I installed the card earlier today tells me that this GPU isn't fully broken, and can surely be saved?
Things I have tried: Switching monitor, switching HDMI cable, unplugging all unneeded accessories, resetting CMOS battery, pressing F12 for Bios on launch, turning everything off and on again, holding buttons down for 30 seconds, resitting the card many times, switching back to the Rx570 and then straight back to the Gigabyte card.
When I boot my PC, all fans turn on as normal, all lights turn on, keyboard and mouse turn on, the only problem is the monitor turning to power saving mode instantly and then staying there.
Nothing has worked. This is the most unsolved problem I have ever had with any PC. Nowhere holds the answers.
Any help would be greatly appreciated. Anything at all.
Thank you.
